Governor Chris Christie of New Jersey is coming to Mitt Romney’s old turf in Boston next month for an exclusive high-dollar fundraiser.

Christie will attend a private dinner on March 1 for 25 to 30 people, who are being asked to donate $3,800 each to the governor’s reelection campaign, according to a copy of an invitation to the event obtained by the Globe. The location has yet to be announced.

“As you may know, he is up for re-election this November and his race will be one of the most closely watched and competitive races in the country this cycle,” Steve Roche, a local fundraiser who is helping to organize Christie’s event, wrote in the invitation. “He could certainly use our help.”

Christie is considered a top contender for the 2016 Republican presidential nomination. He campaigned for Romney last fall, delivering the keynote address at the Republican National Convention in Tampa.

But some Republicans say that his effusive support for President Obama’s response to Hurricane Sandy in the criticial days before the election helped sink Romney’s campaign. Christie has flatly rejected that criticism.
